I'm not a Hellenic pagan, but I am a reconstructionist. I have two comments on this.
First, oh my, how blessed Hellenic Reconstructionists are! What a long list of diverse, firsthand Palæopagan sources that site draws on! If any Heathen could back up any claim about our religion so powerfully, it'd be mic drop time. However, precisely because this is possible in Hellenism, one wonders how much cherry-picking went into that selection.
Second, I don't quite read the webpage's claim the same way you seem to. Right out of the gate they reject moral dualism as a tool to understand reality, insisting instead that we view nature as natural. Then they tie that to the idea that the gods are wholly good by asserting Their utter naturalness.
Rather than being a different way to view the gods, this page seems to invite us to a new way to view goodness. And then, of course, to re-evaluate our previous thoughts about divine imperfection from the new perspective.
Did you forget to include some bad stuff in this list?
